Abstract

Un circuito para demodular una señal de televisión de frecuencia intermedia, que comprende un demodulador que tiene dos salidas antifase, y diseñado como un circuito de conmutación integrado, caracterizado porque dichas salidas antifase (19, 20) están conectadas con la ayuda de un dispositivo serie que comprende al menos dos impedancias (Z1, Z2) tomándose una señal de salida (Uo) de uno de los puntos de conexión (27) del dispositivo serie.
